FS570 to low!

henrik940 · May 26, 2013

Hi. I need a stiffer and/or a longer spring for my rear suspenison.

I'm about 105kg heavy, and the bike gets very low when riding. The bike feels soft and uncomfy during turns. Where can i buy a stiffer spring, and which one?

The FS570 is 15-20mm lower than the FE570. The fork and shock has a spacer inside to limit travel (fork has shorter springs too i believe)

The shock spring is a standard WP/KTM spring. These are 250mm long, and come in many spring rates to accomodate your weight.

The FS comes std with a 8.0kg/mm shock spring, so if you're really sagging that out(measurement, not feeling), then you must be a good bit over 180lbs.

The shock comes out easily with pulling the top and bottom bolt. Once out, the spring comes off easily and you slip on a new spring. Any PDS KTM spring will work for you.
Slavensracing.com has a bunch of springs in stock.

Thanks for a good answere. My dealer recommends 84-250 or 88-250. I have an 80-250 (probably 8.0kg/mm)
I will measure sag and hear what dealer say will be good. Thanks!
